Neither Java nor C++ are 100% OO language, because the implementation
of the primitive types depends on the processor instruction set it's
being ported on.
Nevertheless, it's possible to create a Level instruction set on the
target processor that implements all the basic OO instructions like
new so that primitive types should'nt be wrapped but would directly
represents processor register, wether in Java or in C++.
So does it mean Java and C++ are 100% OO ?
I don't think so.
I think a real 100% OO language is something like
Smalltalk,
because even the block instruction are OO.
So even Java has a little work to do to gain OO heaven!
